Material page for y-strainer screens in Pure Copper. The EMI/RFI shielding and Faraday-cage mesh material. Covers the grade designation (C11000), corrosion and magnetic behavior, cleaning and compatibility notes, and the specifications available.
Why Choose Pure Copper for Y-Strainer Screens
The EMI/RFI shielding and Faraday-cage mesh material. For y-strainer screens, this matters when good atmospheric resistance with a stable patina; outstanding conductivity is the controlling requirement.
Alloy Properties
| Grade designation | C11000 |
|---|---|
| Magnetic response | Non-magnetic |
| Service temperature | approx. +200 °C |
| Corrosion characteristic | Good atmospheric resistance with a stable patina; outstanding conductivity |
Corrosion Behavior in Filtration Service
Copper and brass y-strainer screens resist atmospheric corrosion and fresh water well, tarnishing to a stable patina. Avoid ammonia and ammonium compounds (stress-corrosion cracking of brass) and strong oxidizing acids. In marine service, phosphor bronze outperforms plain brass.
Cleaning & Compatibility
Clean copper-alloy mesh with mild detergent or dilute citric acid; avoid ammonia-based cleaners entirely. In contact with more noble metals in wet service the copper alloy becomes the sacrificial partner — isolate or accept the loss rate.
